After 756 miles travelled, two matches played and four points collected, it was back at Fratton Park.
And Joe Devera admitted he was left ‘deflated’ when a hard week on the road ended in defeat on home turf.
Billy Bodin’s 27th-minute strike settled the match in Torquay’s favour as Pompey put in a wretched performance.
It wouldn’t be until the 86th minute before Richie Barker’s team had their first attempt on target – coming from substitute Wes Fogden.
Despite an improvement from the hosts in the second half, the Gulls held on for a crucial victory in their own relegation fight.
Previous matches saw Barker’s men claim a point in a 2-2 draw at Morecambe and a 1-0 win at Wycombe.
For Devera, those positive results only made Saturday’s loss at home harder to stomach.
He said: ‘The defeat was very deflating, especially after the fact we got two good results away from home.
‘Then we have come back on home turf and lost.
‘That is what’s massively disappointing, for Saturday to happen on the back of doing well away from Fratton Park.
‘If we had won against Torqay we wouldn’t have to be looking over our shoulders at the rest of the table.
‘But unfortunately after the result we are going to have to be looking down there.
‘We have a game on Saturday at Exeter and will look to that to get a good result away from home again.’
Torquay’s win keeps them in the League Two relegation zone but they are now just three points behind Pompey.
Barker’s men sit in 18th spot and did not impress on Saturday.
Chris Hargreaves’ side deserved their lead in that first-half, an opening 45 minutes which would see the Blues booed off at the interval.
Devera added: ‘I just feel they started a lot better than us, they were winning 50/50s, beating us at second balls, they just looked on top of it more than us in that first half.
‘Then in the second half we turned it around.
‘The manager wasn’t happy at half-time.
‘He dug out a few players and we performed much better in the second half.
‘We got a lot of ball into the box and there wasn’t a lot of quality in the final third.’
